JAMES K. SELLARS, OF EAGLE LAKE, TEXAS.

VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 340,624, dated April 27, 1886. Application filed November 6,1885. Serial No. 182,015. (No model.)

To all whom, it may concern.-

Be it known that I, J AMES K. SELLARS, a citizen of the United States, residing at Eagle Lake, in the county of Colorado and State of Texas, have invented a new and useful Improvement in Ventilators,of which the following is a specification, reference being bad to the accompanying drawings:

My invention has relation to improvements in ventilators for tenement-houses, theaters, buildings, railway-cars, 8m; and the novelty consists in the peculiar construction,combination, arrangement, and adaptation of the various parts for service, substantially as hereinafter fully set forth, and specifically pointed out in the claims.

The invention has for its object to provide a ventilator which shall automatically aceommodate or turn the collecting-hood thereof to the direction in which the wind is blowing,to collect and conduct fresh pure air into buildings, cars, dsc. to provide means for regulating the distribution of the air to the compartments or different parts of the buildings, &e.; to diminish the friction and wear between the swiveled collecting-hood and its supporting devices whereby said hood and its attached vane are enabled to turn more freely and readily, and to combine simplicity with strength and durability of construction and thorough effectiveness of operation.

In the accompanying drawings, Figure 1 is a perspective view of my improved ventilator. Fig. 2 is a vertical sectional view thereof. Fig. 3 is aview of the apparatus in position in a factory or other large building, and a series of distributing-pipes. Fig. 4 is a detail view of one of the cap-pieces and regulating-valves.

Referring by letter to the drawings,in which corresponding letters of reference in the several figures denote similar parts, A designates my improved ventilator, comprising a vertical conducting pipe or main B,1nade or constructed in sections and of any suitable material, a collecting-hood, O, rotatively mounted on said pipe or main, a regulating vain or tail connected to said hood, and adapted to keep it in the direction in which the wind is blowing, to collect and conduct the same to the pipe or main B, and outlet-valves I), arranged in the main or pipe and distributing'-pipe, the peculiar construction and arrangement of the several parts above designated being hereinafter fully described.

The collecting-hood 0 comprises a horizontal short tube, 0, a concave-faced disk, 0', having an air-educt port or opening at its middle communicating with the chamber in the tube 0, said hood being secured to the tube at one end and arranged at right angles thereto, a removable regulating tail or vane, cflarranged in a vertical plane in line with the longitudinal axis of the collecting-hood, and having a plug at one end fitted removably in the free end of the tube 0 on the opposite side of the main conductingpipe 'B to the collecting-disk, and of a weight sufficient to counterbalance the said disk and maintain the extreme ends of the collecting-hood tubcin equilibriunnand a short section of conducting pipe or tube, 0 arranged at middle and at right angles to the tube 0, and having an enlarged conductingthroat, c, to permit of the free passage of air from the tube and conductingdisk into the pipe-section a, and thence conducted to the main pipe. T helower end ofthe pipe-section 0* lils in the upperend of the conducting main pipe that projects above the roof of a car or building; and said tube a is provided with a collar or projecting lodge, a, that projects beyond the plane of the outer vertical faces of the main I3, to prevent the entrance of water, ice, into said pipe.

1) designates a crossbar arranged transverse] y of the upper pipe-section, B, that passes through the roof, said cross-bar D projecting beyond the tube B, and fitting in seats or slots I) in the upper endof the main eonductingpipe l), the outer free ends of said cross-bar being secured to the roof or framework of the root of a building or car, to strengthen and brace the upper end of the main conduetingpipe B, and at the same time provide'a bearing or step for the lower end of a supporting-rod, E, that extends vertically within the tube or main B B, and through the upper wall of the tube 0 of the collectinghood.

ff designate two nuts arranged at each end of the supporting-rod E, the nuts at the lower end thereof being arranged to bear on opposite sides of the cross-supporting bar D to hold said rod thereto, and the nuts on the upper end of the supporting-rod fitting or hearing on the outer and inner faces of the upper wall of the tube 6 to hold said rod thereto, whereby a support for the collecting-hood is provided and around which it is capable of turning freely and easily with a minimum of friction and Wear 011 the various parts.

The main conducting pipe or tube B is secured in any suitable or preferable manner in a corner or other convenient point of a building or car, and is provided at its lower end with a cappiece or cover, G, detachably fitted therein, and comprising a disk, 9, either flat or concave, a sleeve, g, and two semicircular arms, 9, arranged and separated a short distance from each other by means of intervening slots This cap or cover also serves as the valve D, to regulate the admission of air into a car or compartment. It is normally placed within the conducting main pipe, so that its disk or cap 9 fits or bears against the lower edges of said pipe; but when it is desired to permit the entrance of air into a car or compartment ofa building it is withdrawn from said pipe a sufficient distance to expose a portion of the slot 9 therein, through which the air enters the compartment from the conducting main pipe, and by regulating the area of the slot exposed in said cap the amount of air admitted can be increased or decreased,as desired Any preferred form of cap may be employed to cover the lower end of the main pipe; but I prefer to employ the regulating-cap G, which also serves as the valve D.

The main conducting-pipe B is provided with a branch distributing-pipe section, 71 as shown in Figs. 1 and 2, and this pipe-section It has a regulating cap or valve, h, similar in construction to the device G, used for the main conducting-pipe, and shown in detail in Fig. 4; or said main conducting tube or pipe may have a series of branch distributing-pipes, i, in the event of the apparatus being fitted to a factory, theater, or other large building, as shown in Fig. 3, and said pipes i are provided with regulating-valves 11, similar in construc tion to Fig. 4, or of any other preferred form.

The pipes may be arranged in any suitable manner to distribute the air and of any preferred material and size desired.

The operation of my invention will be readil y understood from the foregoing description, taken in connection with the drawings.

The regulating vane or tail keeps the collecting disk or hood in proper direction and facing the wind, which is thereby collected and conducted down the main pipe B to the interior of the building or car, and thence carried or distributed properly by the branch distributing-pipes.

The apparatus is simple, strong, and dura ble in construction, does not require any expensive machinery for its operation, and hence can be manufactured and sold at a minimum of cost, does not require attention of attendants, is thoroughly effective in operation, and can be readily taken apart and stored away, if desired.

In the winter-time the collecting-hood and regulating-vane are detached from the pipe 13, and their place supplied by a cap or cover similar in construction to Fig. 4.

By means of the supporting-rod E and its detachable nutsff and the removable pipe section B the collecting-hood can be very quickly and readily detached from the main conducting-pipe and the regulating-vane can be easily removed from the collecting-hood when it is desired to transport or store the same away. The flange e of the collectinghood bears on the upper edges of the main conducting-pipe, and serves to give the collecting-hood a steady motion when rotated in addition to excluding rain and snow from the Said main conducting-pipe.

I am aware that it is not broadly new to provide a main conducting-pipe having a rotating collecting-hood and means for distributing the air into buildings, &c.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a ventilating apparatus for buildings, the combination of a main conductingpipe, B, a collecting hood rotatably and detachably mounted thereon, a removable regulating-vane connected to the hood, a vertical rod, E, inclosed within the pipe and hood and having nutsff at its ends, distributing branch pipe or pipes communicating with the main pipe, and regulating valves adapted to slide in proper openings of the pipes and having slotted arms adapted to be withdrawn from the openings, all arranged and adapted to serve substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto afiixcd my signature in presence of two witnesses.

JAMES K. SELLARS.
